It's time to share Python tips every day again. What do I want to share with you today? Do you want to guess, today I will share with you the batch cropping and merging of vector images.
It sounds a bit incomprehensible, but after reading it, you will understand and expand your knowledge.
Vector batch cropping code
In: chp10\python\vector batch cropping.tbx\vector batch cropping, you can run it directly, right-click to edit and view the code

mdb or not, mdb if checked, gdb if not checked

except arcpy.ExecuteError:
arcpy.AddWarning(arcpy.GetMessages())
The parameters are as follows. The workspace can be a geodatabase (file geodata or personal geodata) or a folder. It is recommended to be a database here.
